Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
What igneous rock is light colored and has a lower density?
Shutup! Jew!
How are light colored igneous rocks different?
Igneous rocks are divided into four groups based on their composition (often determined by observing density and color).Felsic (also called Silicic) igneous rocks have a lower density, and are generally lighter in color (white, tan, pink). They have a higher silica content and a lower iron and magnesium content than the other types of rock. Granite and rhyolite are felsic igneous rocks.Intermediate igneous rocks have a density between felsic and mafic rocks. They have a high silica content and a medium iron and magnesium content. These rocks are usually gray or a similar, medium-toned color. Andesite and diorite are intermediate igneous rocks.Mafic igneous rocks are quite dense, and have a much higher iron and magnesium content than felsic or intermediate igneous rocks. Mafic rocks are usually black or blackish. Gabbro and basalt are mafic igneous rocks.Ultramafic igneous rocks are the densest type, and have the highest iron and magnesium content. Ultramafic rocks are usually (surprise!) green. Peridotite is an ultramafic igneous rock.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
Relationship between silica content and overall color of igneous rock?
They both are the color of an igneous rock.
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
What does the word felsic?
The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.
What color will igneous rock with high levels of silica be?
An igneous rock with a high level of silica will have a light color.
What igneous rock is light colored and has a lower density?
Shutup! Jew!
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

How can mineral composition affect the color of an igneous rock?
Silicate minerals can be light or dark, but Mafic minerals are dark, which is why Basalt appears dark, while Granite is light because Quartz is also light (in colour, not density).

What extrusive rock has a very low density?
An extrusive igneous rock has a very low density. This light colored rock is also known as a volcanic rock.
Does what igneous rocks are made of affect their colour and density?
Based on my knowledge of rocks, I do believe that what rocks are made of will effect their color and density. If a rock is formed from grey ash, then that rock should be grey.

Light-colored igneous rocks with a lower density than basaltic rocks?
Felsic rocks.
